Improve usability of Fonts folder. JIRA issue: CORE-17311 - Modify PIDL design to contain name and filename. - Implement CFontExt:: ParseDisplayName to parsing name as PIDL. - Modify CDefaultContextMenu:: GetCommandString and CDefaultContextMenu:: DoCopyOrCut for DFM_GETVERBA, DFM_GETVERBW, DFM_CMD_COPY, and DFM_CMD_MOVE. - Add IDS_CONFIRM_DELETE_FONT, IDS_CANTDELETEFONT, and IDS_PROPERTIES resource strings. - Add SHMultiFileProperties prototype to <shlobj.h>.
